OK, now this one is a biggie to me. I tweak the Real Tracks a LOT before mixing. I will regenerate a bar, a phrase until I find something I like.

Today, I highlighted a single bar of a vibes track, did the Regenerate Real Track - vibes patch (Selected region)... It DOES regenerate the selected region but also ERASES the next 4 bars ! Nada...wave form is wiped out !?
